META Development: WhatsApp Business API, Facebook, and Instagram
In Costa Rica, Panama, and El Salvador, WhatsApp is where your customers already are, and it matters in the U.S. market as well. WhatsApp Business API integration turns that channel into a working business tool: organized service with multiple agents, automated messaging, notifications, and a direct connection to your internal systems. Done right, it stops being a phone with a chat app and becomes part of your operation.
Grupo EasyPro is a registered META developer. We design and build solutions on the WhatsApp Business API, Facebook, and Instagram, from verifying your business account to deploying AI assistants that handle real conversations. This is not theoretical work for us: EVA, our own AI assistant on WhatsApp, is one of the group's nine proprietary platforms and runs every day on the same technology.
We are technology born in banking. Our team brings deep experience from the banking sector, where customer messaging demands order, traceability, and security. That is the standard we apply to every integration, whether for a financial institution or for a company that simply wants to respond better and faster.
What it includes
- WhatsApp Business API integration with your systems: CRM, ERP, service platforms, or existing databases.
- AI-powered virtual assistants (OpenAI and Anthropic Claude) that understand natural language and hand off to a human agent when it matters.
- Message automation: META-approved templates, notifications, reminders, and conversation follow-up.
- Automated service on Facebook Messenger and Instagram, using the same conversational logic as your WhatsApp channel.
- Voice note processing with Whisper and voice replies with ElevenLabs, for more natural conversations.
- Setup and verification of your WhatsApp Business account and your META business assets.
- Internal dashboards to supervise conversations, with full history and per-user access control.
How we work
We start by understanding how you serve customers today: who answers, which questions repeat, and where conversations get lost. From there we define the conversational flow, deciding what the assistant resolves on its own and where a person steps in. Then we integrate the WhatsApp Business API with your systems, configure the message templates, and test every scenario before going live.
After launch, we stay close to the operation: we review real conversations, tune the assistant's responses, and expand the flows as the channel proves itself. A WhatsApp assistant is not something you deliver and forget; it gets better with use.
Who it is for
This service is built for companies that serve customers on WhatsApp and need to do it in an organized way, at scale: financial institutions, real estate firms, retailers, service companies, and sales or collections teams in Costa Rica, Panama, El Salvador, and the United States. If your team spends the day answering the same questions, or messages get lost across personal phones, there is a clear opportunity to automate.
Technologies we use
Built in-house, proven in-house
The best proof of our capability is that we use this technology every day. EVA, our AI assistant on WhatsApp, handles conversations over the same WhatsApp Business API we implement for clients, and it connects to EasyCore, the group's central platform where more than 130 users work daily. We are registered developers with META, Apple, Google, and Amazon Alexa; we publish our own apps on the App Store and Google Play, plus a skill on Amazon Alexa. Dozens of financial institutions across three countries trust their operations to our platforms.
Frequently asked questions
What is the difference between the WhatsApp Business app and the WhatsApp Business API?
The free app works for a small business with one phone. The API is the enterprise version: multiple agents on a single number, integration with your systems, automation through approved templates, and AI assistants. It requires a properly configured META business account, and we handle that setup for you.
Can you connect WhatsApp to the system we already use?
Yes. Integration with your CRM, ERP, or other internal systems is exactly where the API earns its keep. We work with in-house or third-party systems as long as they expose a way to integrate; when they do not, we evaluate alternatives together with your technical team.
Does the assistant only offer menus, or does it understand natural language?
Both, depending on what each step of the flow calls for. We use OpenAI and Anthropic Claude models for natural-language conversations, and guided structures where the process requires them. We always define when and how a conversation is handed to a person.
Do you have real experience operating this kind of solution?
Yes. EVA, our own AI assistant on WhatsApp, runs on the WhatsApp Business API and is one of the platforms the group operates daily. We do not offer anything we do not use ourselves.
